Improved Materials for Aircraft Self-Sealing Fuel Cell Systems

Abstract

A new self-sealing fuel cell construction was developed utilizing a polyether urethane elastomer which exhibited excellent resistance to cracking and 'chucking out' at a gunfire test temperature of -40 deg F. Efforts made to develop a silicone sealant material with good building tack for use in the development of high temperature resistant self-sealing fuel cells are discussed. A limited amount of effort was devoted to investigating the use of non-sealing fuel line jackets as a means of controlling fuel spraying from ruptured fuel lines. Several commercial foams and thermoplastic sheet materials were evaluated as backing boards for the protection of self-sealing fuel cells. Some of the effort was expended in establishing a reliable method of striking fuel lines with tumbled projectiles.
